Universal Air Bag Over Coil Spring Kits for 2.0" coilover shocks give you on-the-fly ride and height adjustments and will work as a primary rate spring on dual rate setups or as a tender spring on triple rate coilovers. The heavy duty, 3,000 lb rated double-wall air bag features a 2.25" diameter inner sleeve to allow it to slide along the 2.0 shock body while protecting the bags inner wall from rubbing on the shock body threads.

At 0 PSI, the bag sits flat at 4" tall and when fully inflated it will extend over 5" to an extended length of 9.25". Each kit includes a pair of air bags and all of the brackets and hardware needed to install them on any King, Fox, Bilstein, or Sway-A-Way coilovers. For on-the-fly adjustments you will need an on-board air source with air solenoids and any associated switches and relays.
